BROOIVI ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 585,897, dated July 6,1897'.

Application filed December 2, 1895. Serial No. 570,821. (No model.)

T all whom t may concern.-

` tion of the scraper and means for strengthening it and forming bracesintegral with the scraper, whereby the latter is prevented from beingtwisted or bent out of shape.

It also consists in details of construction which will be more fullyexplained by reference to the accompanying drawings, in which- Figure lrepresents a perspective view of a broom embodying my invention. Fig. 2illustrates a scraper-blank. Fig. 3 illustrates the blank with its endsbent at right angles with the body. Fig. 4. is an end view of Fig. Fig.5 is a perspective view of the blank shown in Fig. 3. Fig. 6 shows amodified form of corrugated surface for the scraper.

In the construction of combined brooms and Scrapers it is customary tofix the scraper upon the backA of the broom by nails, screws, orsometimes by ears or lugs which fold down over the ends of the back A.

In my invention the scraper C is preferably stamped out from a sheet ofsufficiently stiff metal bent longitudinally at an obtuse angle, so thatthe portion F will be adapted to be secured by nails or screws passedthrough holes L made along the edge or back of the part A. It will bemanifest that when turned in one direction this part F will be attachedto the edge, and if the plate be turned over it will bring this partupon the top, so that it might be attached in either way, as found mostconvenient or satisfactory. In cutting the plate I have shown it cutwith the ends D diverging from one side toward the other in the form ofa trapezoid, and having slits E made near the ends and parallel witheach other. If desired, these ends D may be formed with prongs G,adapted to be passed into the head A to additionally secure the scraper.These slits extend inwardly from the longest side of the plate, and asthe ends of the plate are made divergent, as before described, thestrips D, which are separated by the slits, will converge from the outerends toward the inner ends of the slits, where they are the narrowest.These partially-separated strips are then bent, as shown in thedrawings, so thata bend or fold is made on the line with the slits, thisfold terminating at the angles where thel narrower sides meet the ends.This forms a bracingpiece which extends in line from the outer portionof the scraper across the end of the head A, to which thesebracing-pieces may be secured by pressing the bent corners G into thehead, and by pins or other fastenings.

It will be manifest that the whole plate may be struck up at a singleoperation by the use of properly-constructed dies and be ready to beapplied to theheadswA.

In order to strengthen that portion of the plate B which projectsoutwardly from the head A, I have found that by forming the dies so asto strike up this surface into corrugations, as shown at II, thisportion of the scraper will be greatly strengthened. These corrugationsmay be of the form shown in Figs. l, 3, and 5 or V-shaped form shown inFig. 6 without departing from the spirit of my invention.

The angular end pieces, which extend down upon each end of thebroom-head to form braces, are fastened by pins or bolts at right angleswith the pull, so that no strain brought upon them will pull them outwithout destroying the wood into which the pins are driven or elseshearing the pins oif entirely.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, ism

l. The combination with a head A, of a scraper made of sheet metal bentat an obtuse angle longitudinally, having one portion attached to saidhead and having its ends bent substantially at right angles to its bodywhereby the bent portions stand on edge and extend down upon the outsideof the ends of the head and are secured thereto.

2. A scraper consisting of a blank of metal trapezoidal in shape andhaving ends diver IOO ging from the upper to the loWel1 edge, said anobtuse angle on a line which intersects the blank being slitted neareach end in line with nnevf` ends of the slits. the angles formedbetween the ends and the y upper side, said ends being folded on theline FREDERICK TITTRAM' 5 of the slitswhel'eby the3T stand on edge andWitnesses: substantially at right angles with vthe blank Y. VITTRAM, andsaid blank being bent longitudinally to V. VITTRAM.
